1. How do Individual Values (IV) work?
▶
Three statistics define a Pokémon: the attack statistic (ATK) defines the damage your Pokémon
will do, the defense statistic (DEF) defines the speed at which your Pokémon will die, the Hit
Points (HP) represents your Pokémon’s stamina.
▶
We consider the example of Mewtwo. Mewtwo’s base statistics are:
Mewtwo
Base_ATK
Base_DEF
Base_HP
How are base statistics computed?
Base stats from Game Boy game
Assume you are very lucky, and you caught a perfect Mewtwo, with (ATK_IV, DEF_IV, HP_IV)
= (15, 15, 15). Your perfect Mewtwo’s stats are:
ATK = (Base_ATK + ATK_IV)
DEF = (Base_DEF + DEF_IV)
HP = (Base_HP + HP_IV)
▶
Depending on the level of your Pokémon, you will multiply all these stats by a coefficient, and
take the floor:
Level 20 Level 25 Level 30 Level 35 Level 40
0.5974 0.667934 0.7317 0.76156384 0.7903
If you level your Mewtwo up to level 40, its statistics are finally:
ATK at level 40
DEF at level 40
HP at level 40
Your friend caught a Mewtwo with (ATK_IV, DEF_IV, HP_IV) = (14, 15, 14). If we do the
same calculations as previous, his Mewtwo, at level 40, will have the following statistics:
ATK at level 40
DEF at level 40
HP at level 40
Surprisingly, his Mewtwo (14, 15, 14) at level 40 and your Mewtwo (15, 15, 15) at level 40 both
have exactly the same statistics!

The Combat Power (CP) formula is:
CP = floor
ATK×

DEF×HP

For Mewtwo (15, 15, 15), at level 40, its CP is floor

For Mewtwo (14, 15, 14), at level 40, its CP is floor
